He’s the first Sox pitcher to go 5-0 through his first five starts since Chris Sale in 2016, and he’s the first pitcher in the majors to win his first five starts with an ERA of 0.58 or lower since the Detroit Tigers’ Jordan Zimmermann (5-0, 0.55 ERA) in 2016.
“He’s been superb,” pitching coach Ethan Katz said during a conference call Saturday. “I’m hoping that this continues. He’s doing all the right things in between, getting his work done, he’s feeling good. Is it realistic that he’ll keep putting these great numbers together? I hope so, but he’s probably going to give up a run here or there at some point.
